@PhoenixMiner, you said:

...
  • Increased the maximum supported DAG epoch to 450. Note that AMD drivers don't allow buffers larger than 4 GB so the biggest possible DAG epoch with current AMD drivers is 378
...

So... Are all 4+ Gb AMD cards (even Radeon VII) become usless, when we reach epoch 378? If AMD didn't fix drivers...
Please, correct me if I wrong.

No,  4+ Gb AMD cards will survive epoch 378+. PM already uses 2 buffers with 2 copies of the DAG  = 6.4GB when you pass parameter -clkernel 3. So there isn't any principle problem the second buffer to contain the second half of the dag instead of its copy.
